Abstract

L'invention concerne un procédé pour produire un détergent en poudre ou une composition pour ce détergent, consistant à effectuer une granulation dans un granulateur à cisaillement élevé ou bas, suivie par une granulation dans un mélangeur à cisaillement très bas, par exemple dans un lit fluidisé. Le procédé permet de produire des poudres ayant une densité apparente choisie dans une plage très large, sans étape d'atomisation.
